Answer: 0.5588 KWh

Step-by-step explanation:

The first step is to calculate the power consumed by applying the formula,

P = IV

where

P represents power

I represents current

V represents voltage

From the information given,

I = 5.03

V = 110

Thus,

P = 5.03 x 110

P = 553.3 W

We would convert it to kilowatt by dividing by 1000. Thus,

P = 553.3/1000 = 0.5533 KW

Amount of energy consumed = power x time

Given that time = 1.01 hours,

Amount of energy consumed = 0.5533 x 1.01

Amount of energy consumed = 0.5588 KWh
